BEST MODE FOR CARRYING OUT THE INVENTION

[The First Embodiment]

The first embodiment of the present invention will be described indetail with reference to the drawings.

FIG. 1 is a front view of a stand type thin design television accordingto the present embodiment. Here, the embodiment is described taking anexample of a liquid crystal display as a display unit 1 for displayinginformation such as video, images and the like. However, various kindsof thin type display devices such as plasma displays, organic EL(electro luminescence) and others can also be employed.

The stand type thin design television includes a display unit 1, a jointbody 15, a stand/pillar structure 30 composed of a pillar 25 and a standbase 29. Joint body 15 is constructed such that it is attached todisplay unit 1 and also attached detachably to pillar 25 fixed to standbase 29, and in the first usage mode where stand/pillar structure 30 isused, joint body 15 is fitted into pillar 25 so that stand/pillarstructure 30 supports display unit 1 while in the second usage modewhere stand/pillar structure 30 is not used, joint body 15 itself isused as a supporting stand for supporting display unit 1.

Since joint body 15 and pillar 25 can be joined to and separated fromeach other as above, it is possible to easily change mode between thefirst and second usage modes. Since joint body 15 is formed so as to bealso usable as a stand, switch between the first and second usage modescan be realized with a simple configuration. Next, each component willbe described in detail.

[Display Unit]

To begin with, display unit 1 will be described with reference to FIGS.1 to 3.

Display unit 1 includes: an approximately rectangular front frame 1 a; aliquid crystal display 3 for displaying video, images, etc., in thefront frame 1; speakers 5 for sound output; a backside cover 7 (FIG. 2);a TV tuner 9 (FIG. 2) provided inside; a detachable chargeable battery11 for power supply (FIG. 2); and a base rail 13 (FIG. 2) formed at thebottom. Display unit 1 can be driven by either battery 11 or anunillustrated a.c., power supply.

Liquid crystal display 3 is able to display video (including video andimage from TV phones) received by TV tuner 9; video and image (includingmotion pictures, still pictures) recorded on and read out from recordingmedia such as, for example, disk media including DVD, MD, CD, FD and thelike and semiconductor memories; and information such as video, images,text, code, etc., from the internet.

Speakers 5 are arranged on both the left and right sides at upperpositions of front frame 1 a and shaped in semicircular forms similar tothe shape of an aftermentioned handle 17 of joint body 15, which looksarch-like (annular) above front frame 1 a, providing balance andstylishness from a design viewpoint and also enhancing strength byvirtue of its curvature. It is preferred that an antenna unit isdisposed at a position as far to the outside as possible for goodreception when display unit is set away from the home position. In thecase of the present embodiment, it is considered that the antenna unitcan be incorporated in speakers 5 which stick out from display unit 1.Further, since display unit 1 is suitable for carriage, it may bangagainst walls etc., during carrying; in such a case, being circularbetter alleviates impacts than being rectangular.

Battery (chargeable cell) 11 (FIG. 2) is disposed in the lower part ofdisplay unit 1 (at the side closer to stand base 29), is set and unsetby opening door 11 a provided in the lower part of backside cover 7 asshown in FIG. 3. Disposition of a heavy part, i.e., battery 11, at thelower part of display unit 1 enhances the stability of the orientationand placement of display unit 1. Here, provision of a power unit such asthe battery etc., in display unit 1 contributes to mobility of displayunit 1; provision of a power supply plug, etc., as another power supplymeans in the display portion enables power supply by plugging it into asocket outlet in order to obtain electricity from a powerline source ata remote site, contributing to mobility. When a plurality of powersupply methods such as battery, power supply plug, etc., are provided,display unit 1 becomes more versatile, specifically it may be driven bythe battery at the remote site while, where there is a socket outlet, itmay be power supplied stably through the power supply plug and also thebattery can be charged.

Base rail 13 functions as a rail for placement of display unit 1 whendisplay unit 1 is separated from stand/pillar structure 30 and isprovided in the bottom face of display unit 1 (on the side close tostand base 29). This can be formed of a material having a non-skideffect, such as rubber, silicone, and the like. The rail is formed in acurved (approximately arced) rail-like (projected) form (having a centeron the display unit side 1) with a length that permits appropriatesetting even if the angle of elevation of display unit 1 is changed.Base rail 13 can be provided with a predetermined length at the bottomof display unit 1, at one or more places so as to present the aboveoperational effect. When a plurality of rails each having a narrowerwidth are provided in parallel to each other, it is possible to realizethe aforementioned operational effect even with a lower amount ofmaterial.

[Joint Body 15]

Next, joint body 15 will be described with reference to FIGS. 1 to 3.

Joint body 15 has a ring-like form, including a grip handle 17, a fixingportion 19 to be fixed to backside cover 7 of the display unit 1, anapproximately bar-shaped stand-cum-joint 23, and a first pivot 21 forjoining the stand-cum-joint 23 with display unit 1 in a rotatablemanner.

In the first usage mode, stand-cum-joint 23 is inserted into an insertspace 27 of stand/pillar structure 30 and functions as a joint forjoining display unit 1 and stand/pillar structure 30. In the secondusage mode, stand-cum-joint 23 functions as a stand for supportingdisplay unit 1. Stand-cum-joint 23 also functions as a removable fittingpart which is inserted to and removed from stand/pillar structure 30 tochange usage mode between the first usage mode and the second usagemode.

Grip handle 17 has an arched (annular) form having a non-skid member 17a made of non-skid rubber, silicone, and the like formed in an arc onthe inner side thereof (FIG. 1).

Grip handle 17 also plays the roles of a structure that can be engagedwith a projection, e.g., a hook 33, formed on a wall 31 etc., as shownin FIG. 6. Since the thickness of first pivot 21 or stand-cum-joint 23(in the front frame 1 a-backside cover 7 direction D) is greater thanthat of the fixing portion 19, grip handle 17 is formed so as to extendobliquely in the thickness direction D of display unit 1, in thedirection away from fixing 19, or to the depth direction D1 of displayunit 1, as shown in FIG. 2. More specifically, with respect to thethickness direction D or the depth direction D1 of display unit 1, theposition or the depth dimension of the engaging portion (top part of thearc) of grip handle 17 engaged with hook 33 is formed to beapproximately equal to the depth dimension of first pivot 21 orstand-cum-joint 23, whereby grip handle 17 can be positioned closer towall 31 so that it can be engaged with a hook 33 that is less projectedfrom wall 31 and so that the display surface of liquid crystal display 3is set approximately parallel to the wall 31 face when the display iswall mounted.

Fixing portion 19 is fixed through backside cover 7 of display unit 1 tothe interior chassis by screws.

First pivot 21 is positioned at a height lower than the midpoint ofdisplay unit 1 with respect to the insert/remote direction H in whichdisplay unit 1 is inserted to and removed from stand/pillar structure30, so as to broaden the angle adjustable range upwards, meeting usageconditions. Also, first pivot 21 holds stand-cum-joint 23 with astrength which keeps the posture of display unit 1 at the set positionafter a rotation with respect to the direction X of the elevation angle.It should be added that the axial direction of the pivot is parallel tothe width direction of display unit 1.

Stand-cum-joint 23 is a structure having a circular cross-section(either solid column or cylinder), including: a rotational part 23 athat is rotatably held on first pivot 21, disposed at the proximal end;and a non-skid/cushioning member 23 b for skid prevention and cushioningfunction, formed of rubber, silicone or the like, at the distal end orat the end opposite to the rotational part 23 a.

As shown in FIG. 2, the longitudinal distance (the distance with respectto the direction from the proximal end to the distal end) of thestand-cum-joint 23 is specified so that, with the length ofstand-cum-joint 23 set parallel to liquid crystal display 3, its distalend is located to extend equal to or beyond the bottom side 1 b of frontframe 1 a of display unit 1. In the present embodiment, the distance tobottom side 1 b of front frame 1 a of display unit 1 is 113 mm and theprojected amount from bottom side 1 b is about 19 mm. Accordingly, asshown in FIG. 1 which is the front view of the state of FIG. 2( b),stand-cum-joint 23 has a length extended downwards below the base side 1b of front frame 1 a.

The reasons for the above configuration are described below:

(1) In a case of a liquid crystal display as a typical example of a thintype display device, referring to the tilt angle, in particular, liquidcrystal displays have the viewing angle problem, and the tilt angleneeds to be able to deal with all usage situations such as when a viewermay watch the liquid crystal display while sprawled, and other cases. Todeal with such situations, when stand-cum-joint 23 is used in the secondusage mode, i.e., as the supporting stand for display unit 1, it issignificantly important that the length of the supporting stand isspecified to project below the bottom side of the display portion whenthe supporting stand is set approximately parallel to the display unit.This setting of the length of projection permits great flexibility ofthe variable angle range.

From a viewpoint of installation space, it is necessary to secure alarge tilt angle in a narrow space. For this purpose, it is desired thatthe joined position of stand-cum-joint 23 to display unit 1 is formed ata position as low as possible. This is because the distance between theground-contact portion (bottom side) of display unit 1 and theground-contact point (distal end) of stand-cum-joint 23 can be shortenedso that it is possible to save space when stand-cum-joint 23 is used asa solo stand for supporting display unit 1.

When first pivot 21 is arranged at a lower position of the display unit,and when the supporting stand as it is set parallel to the display unit,projects slightly below the bottom side of the display portion, it ispossible to obtain a large tilt angle in a narrow space.

(2) In a case of a thin type display device, wall-mounting is one of thefeatures, and for wall-mounting, the display device has the advantagethat the longer the supporting stand, the more stably the display isable to be attached.

Though the above-described grip handle 17, stand-cum-joint 23 and firstpivot 21 are integrally formed as joint body 15 and attached to displayunit 1, they can be of course fixed separately. However, assembly asone-piece structure is easy and has the advantage of manufacturing costsaving.

[Stand/pillar Structure 30]

Referring next to FIGS. 1 to 5, stand/pillar structure 30 composed ofpillar 25 and stand base 29 will be described.

Pillar 25 is a column-like member having a length that permits formationof an insert space 27 enabling the bar-like portion having a circularcross-section, i.e., the part of stand-cum-joint 23 other thanrotational part 23 a, to be inserted and removed, and is fixed uprighton stand base 29.

Insert space 27 is a hole having a circular cross section, and supportsstand-cum-joint 23 in a manner that it receives stand-cum-joint 23therein while non-skid/cushioning member 23 b of stand-cum-joint 23abuts the bottom of insert space 27. The diameter of insert space 27 isspecified in such a size as to permit stand-cum-joint 23 to be freelyinserted and removed and leave a clearance that allows stand-cum-joint23 to rotate about the axis of the longitudinal direction ofstand-cum-joint 23.

Stand base 29 has dimensions that can support display unit 1 at apredetermined height, by means of pillar 25 and joint body 15.

Next, the operational effect of the above-described stand type thindesign television will be illustrated.

To begin with, in the first usage mode in which stand/pillar structure30 is used, display unit 1 is supported by inserting stand-cum-joint 23of joint body 15 that is fixed to the backside of display unit 1 intoinsert space 27 of pillar 25, as shown in (a) to (b) in FIG. 2.Adjustment of the elevation angle X of display unit 1 in this firstusage mode can be made as shown in FIG. 3 by rotating first pivot 21relative to rotational part 23 a of stand-cum-joint 23. Adjustment ofthe direction of display unit 1 in the horizontal direction Y in thisfirst usage mode, can be made as shown in FIG. 4, by rotating displayunit 1 in horizontal direction Y, relative to pillar 25, about thecenter axis of stand-cum-joint 23, or by rotating stand-cum-joint 23 ininsert space 27, about the longitudinal axis thereof. When the displayis used with stand-cum-joint 23 inserted in insert space 27 ofstand/pillar structure 30, the longer the stand-cum-joint 23, the morestably the display unit 1 is supported. However, the length ofstand-cum-joint 23 is enough as long as stand/pillar structure 30 isable to support display unit 1 by insertion of stand-cum-joint 23 intoinsert space 27 of stand/pillar structure 30. Conversely, the length ofstand-cum-joint 23 is insufficient if display unit 1 cannot be supportedby insertion of stand-cum-joint 23 into insert space 27 of stand/pillarstructure 30 and falls down without screws, etc., as in the conventionalexample (FIG. 26). The specific length should be determined based on thesize and weight of display unit 1, the size of base stand 29, the heightof stand/pillar structure 30 and other factors.

Next, in the second usage mode in which, instead of using stand/pillarstructure 30, stand-cum-joint 23 is used as the stand for supportingdisplay unit 1, stand-cum-joint 23 is pulled out from insert space 27 ofpillar 25 by holding grip handle 17, for example, as shown in (b) to (a)in FIG. 2, and display unit 1 is supported by base rails 13 arranged onthe bottom surface of display unit 1 and non-skid/cushioning member 23 bdisposed at the distal end of stand-cum-joint 23, as shown in FIG. 5.

Since stand-cum-joint 23 is provided to be longer than the bottom side 1b of display unit 1, the angle of elevation X of liquid crystal display3 (the vertical angle of the orientation of liquid crystal display 3)can be adjusted stably by taking a large distance between base rails 13and non-skid/cushioning member 23 b when the angle of stand-cum-joint 23is adjusted relative to liquid crystal display 3.

As described above, since display unit 1 is supported by base rails 13provided on the undersurface of display unit 1 and stand-cum-joint 23,the display unit 1 can be installed in a narrow space that affordsplacement of display unit 1 and stand-cum-joint 23.

Also, since the angle of elevation X is adjusted by stand-cum-joint 23,it is possible to adjust the angle of elevation X of display unit 1 witha simple structure and in a limited space.

Further, without the necessity of pillar 25, the display unit can beeasily mounted at the height of a table top, etc., and still the angleof elevation X can be adjusted.

In addition, when, instead of using stand-cum-joint 23 as a stand, griphandle 17 is used as a mounting attachment to wall 31 as shown in FIG.6, display unit 1 can be used as a wall-mounted TV. In this case, sincegrip handle 17 is formed in the arc shape, hook 33 engages the topmostposition of the arc, so that display unit 1 can be mounted in a stableposition without skew.

When the display in the state shown in FIG. 2( a) is engaged on hook 33so as to be used as the wall-mounted TV as shown in FIG. 7,stand-cum-joint 23 may be seen projecting below bottom side 1 b ofdisplay unit 1. In this case, stand-cum-joint 23 is turned about 180degrees about pivot 21 to the upper side of display unit 1 as shown inFIG. 8 so that stand-cum-joint 23 will not be projected (exposed) belowbottom side 1 b, hence preventing the appearance from being marred.Also, when display unit 1 is wall-mounted, it is possible to adjust theangle of elevation of display unit 1 in its wall-mounted state bycontrolling the amount of rotation of stand-cum-joint 23 about pivot 21.

Here, when the depth dimension of display unit 1 at first pivot 21 isformed to be greater than the depth dimension of display unit 1 at thedistal end of grip handle 17, display unit 1 will be set with a certainangle of depression when used as a wall-mounted TV, hence the display iseasy to view from below when it is mounted at an upper position on thewall and suitable as a wall-mounted TV. In this case, stand-cum-joint 23functions as an angle adjuster for adjusting the angle of elevation ordepression of display unit 1.

It is also preferred as a wall-mounted TV if the topmost part of griphandle 17 is projected above the top edge of front frame 1 a as shown inFIG. 7.

Further, stand-cum-joint 23 functions as a stand-cum-angle adjuster whenthe display unit is used as a wall-mounted TV and in the second usagemode.

Additionally, since first pivot 21 is positioned at a height lower thanthe midpoint of display unit 1 with respect to the direction H in whichdisplay unit 1 is inserted to and removed from stand/pillar structure30, stand-cum-joint 23 will not jut out above display unit 1 ifstand-cum-joint 23 is turned approximately 180 degrees about pivot 21.

In the above description of the stand type thin design televisionaccording to the first embodiment, rotation of display unit 1 inhorizontal direction Y is achieved by the means of rotating joint body15 relative to pillar 25, however the present invention should not belimited to this. Next, a second embodiment in which display unit 1,joint body 15 and pillar 25 rotate in horizontal direction Y relative tostand base 29 will be described.

[The Second Embodiment]

The second embodiment of the present invention will be describedhereinbelow in detail with reference to the drawings. Here, the samecomponents as in the above configuration are allotted with the samereference numerals so that their description is omitted while thedifferences from the above configuration will be mainly illustrated.Roughly speaking, the differences from the above embodiment reside inthat the cross section of the stand-cum-joint is modified from a circleto an approximate rectangle (FIGS. 9 and 14) while the shape of pillaris modified in accordance with the change of the shape of thestand-cum-joint (FIGS. 9 and 14), that the pillar is adapted to berotatable in the horizontal direction Y relative to the stand base (FIG.9) and that a remote controller holder 51 for holding a remotecontroller 53 of display unit 1 is provided for grip handle 17 (FIGS. 15to 17). The details will be described hereinbelow.

A stand-cum-joint 35 according to this embodiment includes: a rotationalpart 35 a that is rotatably held on first pivot 21, disposed at theproximal end; and a non-skid/cushioning member 35 b for skid preventionand cushioning function, formed of rubber, silicone or the like, at thedistal end or at the end opposite to the rotational part 35 a, and has across section that is long in the direction of the rotational axis(direction of the support shaft) of the first pivot 21, specifically, anapproximately rectangular cross section, for example.

Forming stand-cum-joint 35 so as to have a rectangular cross sectionthat is long in the direction of the rotational axis of first pivot 21is able to reduce the dimension of the depth direction D1 (FIG. 10) ofdisplay unit 1 of joint body 15 while increasing the stability ofsupporting display unit 1 in the second usage mode (where the display isseparated from stand/pillar structure 30). Specifically, in the case ofstand-cum-joint 23 of the first embodiment, the contact points with themounted site in the second usage mode will form an approximatelytriangular shape, enclosed by base rails 13 and non-skid/cushioningmember 23 b. On the other hand, in the case of stand-cum-joint 35 of thesecond embodiment, since the non-skid/cushioning member 35 b has agreater dimension in the direction of the rotational axis (thelongitudinal direction of the bottom of display unit 1) of first pivot21 than that of the non-skid/cushioning member 23 b, the area enclosedby base rails 13 and non-skid/cushioning member 35 b forms a tetragon ortrapezoidal shape having a long side defined between base rails 13 and ashort side defined by the width of non-skid/cushioning member 35 b. As aresult, if both the stand-cum-joints are set at the same inclinationwith respect to respective display units 1, the stand-cum-joint 35 cancreate a greater supporting area for display unit 1, hence providingimproved stability.

As shown in FIGS. 9 and 10, the longitudinal distance (the distance fromthe proximal end to the distal end) of the stand-cum-joint 35 isspecified so that, with the length of stand-cum-joint 35 set parallel toliquid crystal display 3, its distal end is formed to extend equal to orbeyond the bottom side 1 b of front frame 1 a of display unit 1. In thepresent embodiment, the distance to bottom side 1 b of front frame 1 aof display unit 1 is 113 mm and the projected amount from bottom side 1b is about 19 mm. Accordingly, as shown in FIG. 9 which is the frontview of the state of FIG. 10( b), stand-cum-joint 35 has a lengthextended downwards below the base side 1 b of front frame 1 a.

A pillar 37 of the present embodiment has an elliptic shape in crosssection, as shown in FIG. 14 and is formed with an insert space 39similar to the cross section of stand-cum-joint 35 having anapproximately rectangular shape.

Insert space 39 is a hollow having an approximately rectangular crosssection, and supports stand-cum-joint 35 in a manner that it receivesstand-cum-joint 35 therein while non-skid/cushioning member 35 b ofstand-cum-joint 35 abuts the bottom of insert space 39. The crosssection of insert space 39 is sized so that the stand-cum-joint 35 willbe freely inserted to and removed from the insert space withoutsuffering any uncomfortable backlash when it is inserted therein.Accordingly, rotational force acting on display unit 1 in a horizontaldirection is transferred to pillar 37 by way of joint body 15 andstand-cum-joint 35.

In order to enable relative rotation in horizontal direction Y, pillar37 and a stand base 45 are formed with fitting part 41 and fittingsocket part 43, similar to fitting part 105 and fitting socket part 106shown in the prior art, and fitting part 41 and fitting socket part 43are formed so that they engage each other and are able to rotaterelative to each other.

Also, a smoother 47 is provided at the bottom of pillar 37 on the sideof stand base 45 in order to suppress generation of uncomfortablefriction sounds and contact damage during its rotation relative to standbase 45. The material of smoother 47 can be selected as appropriate,taking into account the material of stand base 45; for example,plastics, hard rubber, silicone, and other materials can be used.

In the joint portion between pillar 37 and stand base 45, in order torealize smooth rotation of pillar 37 and in order to suppress generationof uncomfortable fiction sounds and contact damage during the rotationrelative to stand base 45, a clearance 49 is formed so as to becomegreater as it goes away from the rotational center, i.e., fitting part41 and fitting socket part 43, as shown in FIG. 9. Here, stand base 45has dimensions that can support display unit 1 at a predetermined heightby means of pillar 37 and joint body 15.

In the present embodiment, a remote controller holder 51 for holdingremote controller 53 of display unit 1 is provided for grip handle 17,as shown in FIGS. 15 to 19. Since display unit 1 of this embodiment canbe used separated from pillar 37, there is a risk of remote controller53 being away from display unit 1, which produces inconvenience.Provision of remote controller holder 51 in grip handle 17 thatseparates from pillar 37 together with display unit 1, makes it possibleto move the display unit with remote controller 53 to another location,it is possible to prevent remote controller 53 from being carelesslymislaid or lost.

The remote controller holder 51 in this embodiment is composed of, asshown in FIG. 18, attachment segments 51 a to be attached to the displayunit 1 side and a pair of claws 51 b for engaging remote controller 53to hold it.

Specifically, when remote controller 53 has a configuration thatsignificantly tapers from one end 53 a to the other end 53 b as shown inFIG. 19, remote controller 53 may be inserted with its tapered end 53 bfirst into the hold of paired claws 51 b as shown in FIG. 19 so that thefront end 53 a side, which is formed greater in width, are caught by theclaws and engaged thereby as shown in FIG. 15. In this case, if claws 51b and 51 b of remote controller holder 51 are formed so as to beinclined appropriately so that their distance becomes smaller from theupper to lower sides of display unit 1, the tapering remote controller53 can snugly fit therein, which is preferable.

When remote controller holder 51 is formed of a material such as aplastic, etc., which has appropriate flexibility and is formed so thattwo claws 51 b and 51 b can hold remote controller 53 with pressure,inserting remote controller 53 into remote controller holder 51 with acertain force causes claws 51 b to elastically deform to thereby holdremote controller 53 in remote controller holder 51 in a grippingmanner.

When claws 51 b of remote controller holder 51 are designed so as toconstrict remote controller 53 with some strength when held in place, itis no longer necessary to shape remote controller 53 with the one end(53 a side) enlarged and the other end (53B side) reduced in size, hencethe holder is able to hold remote controllers 53 of various shapes.

It should be noted that the shape and position of attachment of remotecontroller holder 5 and other configurations are not limited, and theremote controller holder may be attached directly to the backside ofdisplay unit 1. That is, it may have any shape, configuration and may bepositioned at any place as long as remote controller 53 can be carriedtogether with display unit 1. Also, it may assume any shape as long asit can fit with the remote controller. Further, it is possible toprovide a configuration such that remote controller 53 is fitted intodisplay unit 1 itself so as be carried together.

Up to now, the configuration and operational effects have been describedby referring mainly to the differences of the configuration in thesecond embodiment, it goes without saying that the operational effectsdescribed in the first embodiment can be also obtained.

It should be also noted that the above-described stand-cum-joint 35 hasan elongated, approximately rectangular cross section, long in the axialdirection of first pivot 21, and it is not limited to the approximatelyrectangular shape, but stand-cum-joint 35 may have any shape as long asthe rotation of stand-cum-joint 35 can be transferred to pillar 37.

It also goes without saying that the remote controller holder 51described in the second embodiment can be applied to the configurationof the first embodiment.

The first and second embodiments are constructed so thatstand-cum-joints 23 and 35 are pulled out from insert spaces 27, 39,respectively. An unillustrated coupling pin for removal prevention ofstand-cum-joint 23 or 35 from corresponding insert space 27 or 39 may beprovided so as to be inserted into stand-cum-joint 23 or 35 bypenetrating through pillar 25 or 37. This configuration makes itpossible to move display unit 1 as a whole up to stand base 29 or 49, bylifting grip handle 17. However the anti removal means is not limited toinsertion of a coupling pin. This will be further detailed next as thethird embodiment.

[The Third Embodiment]

Next, the third embodiment of the present invention will be described indetail with reference to the drawings. Here, the same components as inthe above configuration are allotted with the same reference numerals sothat their description is omitted while the differences from the abovesecond embodiment will be mainly illustrated. Roughly speaking, thedifferences from the above second embodiment reside in that a hollow 59for removal prevention and a projection 61 for insert directionrestraint are provided for the stand-cum-joint, that the length of thestand-cum-joint is changed to equal to or shorter than that to thebottom side 1 b of front frame 1 a of display unit 1 when it is setparallel to liquid crystal display 3 (FIGS. 20 and 21), that an antiremoval device of the stand-cum-joint is provided for the pillar (FIGS.20 to 24), that projections 55 are formed in first pivot 21 while theshape of the upper end of the pillar is modified in order to limit theangle of elevation of display unit 1 when and after the stand-cum-jointis joined to the pillar (FIGS. 20 and 21), and that an indicating devicefor recommending the angles of elevation of display unit 1 is providedbetween first pivot 21 and the stand-cum-joint (FIG. 25).

[Stand-cum-joint 57]

A stand-cum-joint 57 of this embodiment has an approximately rectangularcross-section as of stand-cum-joint 35, but is formed with a lengthwhich does not exceed the bottom side 1 b (base rail 13) of front frame1 a of display unit 1 (including the equal length) and can at leastfunction as a stand for supporting display unit 1 in the second usagemode. Specifying the length of stand-cum-joint 57 as above puts thecenter of gravity of display unit 1, in the second usage mode, at apoint on the stand-cum-joint 57 side (the backside cover side), wherebyit is possible to reliably prevent damage of the delicate display screenbecause even if an external force toppling display unit 1 acts thereon,the display unit only falls down to the backside cover 7 side.

Stand-cum-joint 57 has a hollow 59 (FIG. 20) for preventing itsseparation from the joined state to a pillar 65 and a restraintprojection 61 (FIG. 21) for limiting the direction of its insertion intopillar 65 to one way only.

[Anti-removal Device on the Stand-cum-joint Side]

Anti-removal hollow 59 (FIG. 20) is located on the opposite side of theface opposing display unit 1 when the smoother/cushioning member 35 b ofstand-cum-joint 57 is positioned at the bottom side 1 b of display unit1, and formed closer to the free end side (the smoother/cushioningmember 35 b side) with respect to the length of the stand-cum-joint(rotational part 35 a-smoother/cushioning member 35 b direction). Thisanti removal hollow 59 has an approximately a triangular prism-likeshape, long in the width direction of stand-cum-joint 57, and the hollowis formed so that the depth of the hollow becomes greater towards thefree end side (the smoother/cushioning member 35 b side).

[Insert Limiting Device]

Restraint projection 61 (FIG. 21) is provided at the opposite side ofanti removal hollow 59 of stand-cum-joint 57, and is a hill-shapedportion or a convex portion, projected in the direction perpendicular tothe direction of insertion of stand-cum-joint 57 into pillar 65 (also tobe abbreviated as “direction perpendicular to insertion” in some cases).Restraint projection 61 is one example of the insert limiting device forguiding the insertional direction of stand-cum-joint 57 into pillar 65to only one way, and the present invention should not be limited to theposition and configuration of restraint projection 61. When, forexample, the insert limiting device is formed with a projection orgroove (recess, hollow and cutout), a projection or groove such as thehill shape, convex shape and the like, projected or recessed in thedirection perpendicular to insertion may and should be formed at theportion of pillar 65 where stand-cum-joint 57 is inserted.Alternatively, without forming any projection or groove, the sectionalshape of stand-cum-joint 57, i.e., the shape to be inserted into pillar65 may be formed with a sectional shape, such as a trapezoid, etc.,which can limit its insertion to only one way.

Thus, provision of the insert limiting device as above makes it possibleto prevent loss of balance in the first usage mode due to placement ofdisplay unit 1 in an unexpected position or prevent the apparatus fromfalling over. That is, in order to prevent pillar 65 from falling overdue to the center of gravity shifting to the display unit 1 side, standbase 45 (FIG. 21) is formed so as to extend greatly to the displayscreen side compared to the rearward from pillar 65. Nevertheless, thereis a risk of falling if stand-cum-joint 57 is accidentally inserted byturning front side back, so the provision of the insert limiting deviceundoubtedly eliminates the possibility of such falling.

[Rotation Restraint Structure]

In order to limit the angle of elevation of display unit 1 when andafter coupling between pillar 65 and stand-cum-joint 57, projections 55are formed on first pivot 21 (FIGS. 20 and 21).

Projections 55 are formed on first pivot 21 along the direction ofrotation of stand-cum-joint 57. In the present embodiment, the surfaceof first pivot 21 where no projection 55 is formed, is definedapproximately semi-circularly, equidistant from the center of therotational axis of stand-cum-joint 57 while the portion with projection55 is defined by a longer distance away from the center of therotational axis of stand-cum-joint 57 than that in the area withoutprojection 55. Thereby, in the state where projections 55 interfere withpillar 65, the display takes an unstable position in which the antiremoval device does not function correctly, so that the user will bereminded that the attachment has been done beyond the permissibleposition range.

Additionally, even in the first usage mode in which the anti removaldevice functions correctly, if an attempt to tilt the display withrespect to the direction of elevation is made toward an imbalancedposition, the underside faces 55 a of projections 55 interfere andcollide with an rear edge 69 a (FIG. 21) of a upper face 69 of pillar65, so that a further rotation in the direction of elevation is limited,to thereby prevent imbalance usage in the first usage mode beforehand.

Further, the disposition of projections 55 in the area, e.g., firstpivot 21, which engages or is close to the upper face 69 of pillar 65and rotates together with display unit 1, makes it possible to putpositional restraint when set into the first usage mode and limitforcible rotation of display unit 1 with respect to the direction ofelevation in the first usage mode, without limiting the angle ofelevation of display unit 1 in the second usage mode. As a result, it ispossible to set up the different permissible elevation ranges of thedisplay unit 1 between in those in the first usage mode and those in thesecond usage mode, hence safe use conditions meeting the usage modes canbe secured.

It should be understood that as the means for implementing the aboverestraint, other configurations, in which the distance from therotational axis of stand-cum-joint 57 to the surface of first pivot 21is changed (the distance is made longer for the restraint range), can beused; for example, in place of use of projections 55, the surface offirst pivot 21 may be formed in an elliptic configuration, etc., toobtain the same operational effects. Here, in the present embodiment,projections 55, or projections 55 and rear edge 69 a of pillar 65 areformed so that the display may be inclined at a tilt angle of about 10degrees from the direction perpendicular to the mounted surface ofdisplay unit 1.

[Grip Handle 17 b]

In order to carry display unit 1 easily, a grip handle 17 b is provided.Any configuration will work as this grip handle 17 b as long as it canbe gripped. In the present embodiment, in order to ease joining andseparation between pillar 65 and stand-cum-joint 57, grip handle 17 b isdesigned to be less inclined relative to fixing portion 19 than griphandle 17 is. This prevents swaying of display unit 1 when grip handle17 b is held, hence makes it possible to smoothly change the way ofusage between the first and second usage modes.

In addition, circular grip handle 17 b is convenient for carriage andwall-mounting, rectangular and triangular grip handles, however, arealso suitable for carrying and wall-mounting, respectively.

[Pillar 65]

Roughly specking, pillar 65 differs from pillar 37 of the secondembodiment, in the shape of the upper face designated at 69, the shapeof an insert space 71, provision of an opening/closing lid 73, an antiremoval device 77 of stand-cum-joint 57 and the like (FIGS. 20 to 24).

Upper face 69 of pillar 65 is formed becoming gradually higher from thescreen side of display unit 1 toward the backside, so as to mate withthe underside of first pivot 21. This configuration is able to reducethe gap between pillar 65 and first pivot 21 in the first usage mode andhence produce in appearance a sense of unity of the separable displayunit 1 side and the pillar 65 side, making success in design.Additionally, in a case where projections 55 come into contact withupper face 69 when stand-cum-joint 57 is inserted into pillar 65, upperface 69 and the undersurface of first pivot 21 do not mate with eachother, forming gaps, which helps the user to recognize occurrence of animproper insertion.

Insert space 71 is a hole into which stand-cum-joint 57 is inserted, andhas a shape approximately similar to the sectional shape ofstand-cum-joint 57 with restraint projection 61, cut on a planeperpendicular to the direction of insertion (FIG. 22).

[Interference Protector]

Cushioning members 72 a and 72 b, made up of block-like, bar-like and/orplate-like rubber, plastic, silicone or the like as the interferenceprotectors for keeping a predetermined gap with stand-cum-joint 57 areprovided in insert space 71, at positions above the midpoint of thelength of insert space 71 or closer to the opening side. Cushioningmembers 72 a and 72 b may be provided annularly or partially withrespect to the directions perpendicular to insertion. Sincestand-cum-joint 57 fitted in insert space 71 is supported inside insertspace 71, with the side of its shaft abutted by cushioning members 72 aand 72 b and the distal end abutted by non-skid/cushioning member 35 b,it is possible to reduce uncomfortable shaking of display unit 1relative to pillar 67 and generation of noise due to interference.

Further, when the portion, designated at 89, in insert space 71 opposingnon-skid/cushioning member 35 b of stand-cum-joint 57 or its vicinity isformed of a magnet while the non-skid/cushioning member 35 b is formedof metal, the distal end of stand-cum-joint 57 can be attracted to themagnet at the bottom of insert space 71 in the first usage mode, henceit is possible to reduce uncomfortable shaking of stand-cum-joint 57inside pillar 67 and generation of noise due to interference.

[Lid Member 73]

Opening/closing lid 73 is a lid member that is hinged at its one side bythe top inside insert space 71 and is continuously urged in thedirection it closes the opening of insert space 71 (FIGS. 22 and 23).Since opening/closing lid 73 closes the opening of insert space 71 inthe second usage mode, it is possible to avoid entering dirt into insertspace 71.

[Anti-removal Device on the Pillar Side]

FIG. 23 is a perspective cutaway view cut along a plane B-B in FIG. 22;FIG. 24 is a perspective view showing the part of an anti removal device77 in FIG. 23, viewed from the rear side; and FIG. 25 is a perspectiveview for explaining the operation of anti removal device 77 when anactuator 79 is pressed from the state shown in FIG. 24.

As shown in FIG. 23, anti removal device 77 comprises: user actuator 79;a latching/unlatching part 85 which, in the first usage mode, isinserted into and meshed with anti removal hollow 59 (FIG. 20) and comesout from the anti removal hollow 59 by the operation (pressing, forexample) of actuator 79 so as to disengage the meshing; a frame 81 forhousing actuator 79 and latching/unlatching part 85 and allowing them toreciprocate; and springs 83 and 87 for respectively urging actuator 79and latching/unlatching part 85 outwards from the interior of frame 81.

Actuator 79 has an operating button that is rounded at edges with aconcavity at its center in order to produce a greater contact area witha finger so as to disperse its pressing force. The portion, oflatching/unlatching part 85, to be inserted into anti removal hollow 59has an approximately triangular prim-like shape similar to the shape ofanti removal hollow 59. Sliding movement of actuator 79 and that oflatching/unlatching part 85 inside frame 81 are approximatelyperpendicular to each other, so that the directions of urging of springs83 and 87 are also approximately perpendicular to each other.

As shown in FIG. 24, one side wall of frame 81 is formed with a firstguide slot 81 a for guiding actuator 79 in its moving direction and asecond guide slot 81 b for guiding latching/unlatching part 85 in itsmoving direction, and a guide projection 79 a of actuator 79 is engagedwith the first guide slot 81 a and a link rod 85 a oflatching/unlatching part 85 is engaged with the second guide slot 81 b,respectively in a reciprocating manner.

Actuator 79 has a link slope 79 b as an inclined surface for pressingand moving link rod 85 a along second guide slot 81 b with the movementof actuator 79.

In the above arrangement, when grip handle 17 b is drawn up withstand-cum-joint 57 coupled with pillar 65 (FIG. 23), a first abutment 85c of latching/unlatching part 85 and an opposing, second abutment 59 aof anti removal hollow 59 of stand-cum-joint 57 interfere with eachother, so that pillar 67 and stand base 45 can be lifted together topermit movement in the first usage mode.

When usage is shifted to the second usage mode, pressing actuator 79opposing the urging force of spring 83, as shown in FIGS. 24( a) and24(b), causes link slope 79 b to press link rod 85 a while guideprojection 79 a moves within first guide slot 81 a, whereby link rod 85a moves rearwards (in the direction in which latching/unlatching part 85is pulled out from anti removal hollow 59) within second guide slot 81d, simultaneously, latching/unlatching part 85 having the link rod 85 amoves rearwards opposing spring 87, and latching/unlatching part 85 iswithdrawn from anti removal hollow 59. Thus, when grip handle 17 b ispulled up while actuator 79 is being pressed in the insertionaldirection H1 of stand-cum-joint 57 being inserted, stand-cum-joint 57 ispulled out from pillar 67, while first abutment surface 85 c oflatching/unlatching part 85 does not interfere with second abutmentsurface 59 a. At this moment, since force is applied and directed in thedirection H2 in which stand-cum-joint 57 is removed from thestand/pillar structure by pulling up grip handle 17 b while lifting ofthe pillar portion is held back by the applied force on actuator 79 inthe insertional direction H1 of stand-cum-joint 57, hence theapplication of the force in the opposite direction enables easy andstable detachment.

[Indicating Device]

FIG. 25 shows a sound generator 91 for first pivot 21 (FIG. 20) androtational part 35 a of stand-cum-joint 57, as one example of indicatingdevice of recommended angles of elevation of display unit 1.

Sound generator 91 comprises: a roller 93 that is rotatably arranged inan long hole 22 c (FIG. 25( b)) formed in a bearing portion 22 fixed tofirst pivot 21; a plate-like roller receiver 95 having cutouts 94 a and94 b to be engaged with the roller 93; and an urging means 97 constantlyurging the roller 93 to the roller receiver 95 side.

Bearing portion 22 has a fixture face 22 a to be fixed to first pivot 21by screws, etc., a flat pivot 22 b for axially supporting a rotationalshaft 36 of rotational part 35 a, and long hole 22 c for rotatablyholding roller 93 in the flat pivot 22 b.

Long hole 22 c is located close to a bearing 22 d of rotational shaft 36and opposing cutouts 94 a and 94 b, and loosely holds roller 93 with aproper gap with respect to its minor axis. Movement of roller 93 in thelongitudinal direction of long hole 22 c is limited at one side bybearing 22 d and at the other side by a proximal portion 97 a of urgingmeans 97. Here, long hole 22 c may and should be sized and configured soas to at least permit roller 93 to move in the direction of urging bythe urging force of urging mans 97.

Roller 93 used here is spherical, but the roller may be of a rotatableshape, e.g., cylindrical shape and conical shape. Roller 95 is formed ofmetal, but may be formed of any material such as metal, resin, etc.,taking into account the contact sound with roller receiver 95 duringrotation, and the indication sound when engaged with cutout 94 a or 94b.

Roller receiver 95 is a plate-like element projected as a flange fromrotational shaft 36 axially supported on flat pivot 22 b and has annularcutouts 94 a and 94 b positioned equi-distant from the rotational shaft36. Roller receiver 95 is formed in a flat plate-like form but may beformed with a guide rail for roller 93 at the area where it abuts roller93. This functions as guide in the moving direction of roller 93 withrespect to roller receiver 95, hence enabling smooth rotation. Here, theguide rail may be formed by, for example, a groove having a width thatcan guide roller 93.

Cutouts 94 a and 94 b are formed with an opening that will not permitthe roller 93 to pass through, and shaped annularly having a diametersmaller than that of roller 93 in order to enhance the stability ofroller 93 fitted therein, and having an effect of centering of roller93. Further, the opening rims of cutouts 94 a and 94 b are formed with acurved surface (contact surface) 94 c fitting the roller 93, so as toenhance the stability and centering effect of roller 93 meshing cutouts94 a and 94 b.

Cutout 94 a is formed at such a position as to oppose roller 93 when, inswitching usage from the second usage mode to the first usage mode,stand-cum-joint 57 is set at a recommended angle for joining itself topillar 65, or set approximately parallel (at an angle of about 0 degree)relative to display unit 1. Cutout 94 b is formed at such a position asto oppose roller 93 when, in the second usage mode, display unit 1 isset at a recommended angle, e.g., the display screen of display unit 1is tilted at about 15 degrees relative to the direction perpendicular tothe mounted surface. It should be noted that the number and positions ofcutouts are not limited to the above configuration, it is possible toselect any positions depending on the events which should be indicatedto the user as recommended angles.

Urging means 97 constantly urges roller 93 toward the roller receiver 95side, and is fixed at proximal portion 97 a to flat pivot 22 b on itsroller receiver 95 side with screws and turned back in a U-shape at theedge of flat pivot 22 b so that the flat surface 97 b in the vicinity ofthe free end presses roller 93 against roller receiver 95 with apredetermined urging force.

In the above arrangement, as stand-cum-joint 57 is pivoted from thestate where roller 93 is engaged with cutout 94 a, rotational shaft 36and roller receiver 95 rotate together opposing the urging force actingon roller 93 from urging means 97 and the centering force acting betweenroller 93 and cutout 94 a, and roller 93 rolls on the flat surface ofroller receiver 95. As roller 93 rolls, and when it fits and becomesengaged with curved surface 94 c of cutout 94 b, an indication sound or“click” indicating a recommended angle arises from the urging force fromurging means 97 and the centering force between roller 93 and cutout 94b. Thus, the user is given notice of a recommended angle, hence is ableto comprehend safe usage positions. This results in a user-friendlyapparatus. Similarly, in the case of rotation from cutout 94 b to cutout94 a, the user is able to know the angle of stand-cum-joint 57 to beinserted into pillar 65 from the indication sound or “click” indicatinga recommended angle, hence recognize the fact of safe set position.

Here, urging means 97 is not limited to a leaf spring, but an elasticmember, e.g., rubber, which continuously presses roller 93 againstroller receiver 95 may be used.

Additionally, the indicating device here was described by taking aconfiguration that aurally informs the user of a recommended angle, forexample, sound generator 93, but it should not be limited to thisconfiguration as long as it can produce a sound with change of theangle. It is also possible to obtain the same effect by informing theuser of the recommended angle with a visual method using, for example,light emitting devices, light-emitting members, instead of indicationsound.

It also goes without saying that the same operational effects can beobtained by applying the third embodiment to the configuration of thefirst embodiment.

Next, the case in which the battery incorporated in the display unit ischarged in the first usage mode will be described hereinbelow as thefourth embodiment. Here, the fourth embodiment will be describedreferring mainly to the differences from the third embodiment.

[The Fourth Embodiment]

In a stand-cum-joint 57 b of the present embodiment, as shown in FIG.26, a connector portion C1 that is electrically connected to battery 11incorporated in display unit 1 is formed as part of non-skid/cushioningmember 35 b of the stand-cum-joint 57 of the third embodiment.

Connector portion C1 of the present embodiment has a contact with anaftermentioned connector portion C2, exposed from non-skid/cushioningmember 35 b. The configuration of the contact is not particularlylimited; flat-shaped, female pin type or any other type contact can beused.

A lead wire L is connected from connector C1, passing through theinterior of stand-cum-joint 57 to battery 11.

On the stand/pillar structure 65 b which is the power supply side toconnector C1, connector portion C2 is arranged at such a position in theopposing portion 89 of the third embodiment as to oppose the connectorportion C1, whereby electric connection with the connector portion C1 isestablished in the first usage mode.

The connector portion C2 is connected to a d.c. power supply unit(including an AC-DC converter) P2 for converting a.c. current from ana.c. power source plug P1 into d.c. current.

Accordingly, in the first usage mode, when power source plug P1 isinserted into an unillustrated plug socket, the d.c. current from powersupply unit P2 is supplied to battery 11 by way of connector portion C2,connector portion C1 and lead wire L.

With the above configuration, in the second usage mode it is possible tocarry only display unit 1 and operate it with the power supply frombattery 11, at another location to which the display is carried. In thefirst usage mode, while battery 11 provided in display unit 1 ischarged, display unit 1 can be used for display purposes, thus making itpossible to provide improved usage convenience. It goes without sayingthat current from d.c. power supply unit P2 can be supplied not only forcharging of battery 11 but also for power supply to display unit 1itself.

Also, the positions of attachment of connector portions C1 and C2 andtheir shapes, etc., are not limited as long as the positions, shapes,etc., are designed to establish electric connection in the first usagemode.

As has been described heretofore, according to the present invention,without limitation of the mounting space, the display unit can beefficiently used in various usage modes such that the display may bemounted in a narrow place or moved to a table top or wall-mounted, thusit is possible to provide a highly versatile display apparatus.
